This is a Project work undertaken in context of partial fulfilment of partial B.tech. We have tried our best to make the project routing with network security. The structure of this project based on back end structure of internet. This project is combination of two things like networking and network security. Computer Networking is a very vast project in the present developing era of electronics and communication. Now a day, computers are used in a wider range. All the organizations are using multiple computers within their departments to perform their day to day work. Computer network allows the user to share data , share folders and files with other users connected in a network. Computer Networking has bound the world in a very small area with it wide networking processes like LAN, MAN, WAN.
Routing is a process or technique to identify the path from one network to another. Routers don’t really care about hosts—they only care about networks and the best path to each network. TYPES OF ROUTING Static routing, Default routing, dynamic routing.
In static routing an administrator specifies all the routes to reach the destination. Static routing occurs when you manually add routes in each router’s routing table. By default, Static routes have an Administrative Distance (AD) of 1 Default routing is used to send packets with a remote destination network not in the routing table to the next-hop route. Default routing is also a type of static routing which reduces the routing overhead & default routing is also used with stub networks. Stub networks are those having a single exit interface. Dynamic routing is when protocols are used to find networks and update routing table on routers. A routing protocol defines the set of rules used by router when it communicates routing information between neighbor routers. In dynamic routing, we will enable a routing protocol on router. This protocol will send its routing information to the neighbor router. The neighbors will analyze the information and write new routes to the routing table. Network security is the most widespread secure service. It allows you to deny a other network.
